Fuel Saving Tips
Unless you live in a very cold climate or drive an old vehicle that is 25+ years old you shouldn't need to warm up your engine. Modern engines will run fine from start with auto chokes etc. You are just wasting fuel while idling and waiting. Get in it and go! Its a good idea not to put the vehicle under heavy load right away until warmed up, but that should only take a few minutes in normal conditions.
